Answer:
The correct answer is A. The bomb dropped on Hiroshima killed 70,000 people instantly.
Explanation:
At the time of the bombing, Hiroshima was a city of some industrial and military importance. Some military camps were in the vicinity, including the headquarters of the Fifth Division and those of the Second General Army of Field Marshal Hata Shunroku, who commanded the defense of the entire southern part of the country. Hiroshima was a minor supply and logistics base for the Japanese militia. The city was a communication center, storage place and a meeting area for the troops.
Although US aircraft had previously launched pamphlets warning civilians of aerial bombings in 12 other cities, Hiroshima residents were never warned of a nuclear attack. Between 70,000 and 80,000 people, about 30% of Hiroshima's population died instantly, while another 70,000 were injured. About 90% of doctors and 93% of nurses in Hiroshima died or were injured, since most of them were in the center of Hiroshima, the area that received the greatest impact.
